'GAS-BURNER.

Speccaton'of Letters Patent.

Patented Jan. 1, 1907.

To all whom t may concern.-

Beit known that I, PHILIPP SEILEE, a citizen of the United States, and a resident of Chicago, in the county'of 'Cook and State of IllinoIs, have invented certain Improvements in Gas-Burners, of which the following is a speciiication. y

This invention relates to certain improvements in gas-burners, and particularly in burner-tips, such as are commonly employed .in gas-lighting systems and the object of the invention is, in part, to provide a burner-tip of this character of a simple and inexpensive nature which may be chea ly and conveniently formed up from metall), and, in part, to provide for use within and in connection with such tips means for regulating the flow of gas therethrough, so that ilickering is prevented and a steady and uniform flame is insured despite ordinary variations in gas-pressure'in the mains. 4 y

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved burner-tip whereby certain important advantages are attained and the device is rendered simpler, cheaper,A and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims. K

In the accompanying drawings, which serve to illustrate my invention, Figure l is a side elevation of a burner-tip constructed according to my invention; and Fig. 2 is a view of the tip similar to Fig. l, but taken in a direction at right angles to ythe direction of vision in Fig. 1. Fig. 3 is a sectional view taken axially through the improved burnertip, showing the same applied to a pillar for use.

of the regulator-cap 'therein As shown in the views, the improved gasburner tip is formed up from an integral piece of metal, which may be conveniently of aluminium in the form of a blank of sheet metal or metal tubing, the body portion of said tip being made of a somewhat vtapered form,l as shown at 1, in 'order that the tip -gas-passage within the burner-tip Fig. 4 is an underside view of the improved burner-tip, showing the arrangement may be snugly fitted in the ordinary way within the upper tapered en d of the bore or hollow of the pillar as seen in Fig. 3.

2 represents the bore or hollow forming a bod 1, and this bore or hollow is preferab y forriied, as herein shown, with straight sides, although, if desired, the walls thereof may be ta ered reversely to the taper of the outer wa ls of the tip-body without material departure from the spirit of the invention.

3 is the regulator-cap, also formed, by preference, of someA such material as aluminium, with flanged edges 4, adapted to snugly iit within the walls of the burner-tip body l at the lower open end thereof and 5 is a central gas-aperture in said cap 3 and of a diameter to permit a regulated supply of gas to be received through it from the hollow ofthe pillar into the hollow of the burner-tip body l. Within the lower yend of the burner-tip body are arranged spaced screens '6` 6, of fine meshed wire-netting, which are held in place by frictional engagement of their edge portions upon the walls of said body, so that they may be conveniently applied or removed, and said screens are spaced apart from each other to produce ak chamber between them, as shown at 7, in which chamber is adapted to be received a packing of asbestos or other suitable material for retarding.

the flow of gas suiiicien'tly to adapt the burner-tip for use in connection with different gas-pressures. By this arrangement it will be seen that the regulator-cap 3 may be removed from the tip, after which one or both of the screens 6 6 may be removed, and the packing of asbestos, 'if such be employed, maybe th'en adjusted to accommodate the burner-tip to various gas-pressures. The asbestos or other packing may, if desired, be dispensed with, and I have found 'that 'an additional screen of wire-gauze similar to the screens 6 6, arranged Vacrossl chamber 7,

serves the purpose of said asbestos packing efficiently in many cases. y

At opposite sides of the upper end of the burner-tip body l the metal from which the tapered tubular walls thereof are made is inwardly pressed, as seen at 8 8, to form a par- IOO tial closure or inwardly-directed. flange at each side of said upper end, and at the inner portions of said flanges S 8, at opposite sides of said upper end of the tip, are produced rounded and upwardly-extended parts 9 9, integral with said flanges 8 8 but extended upward above said flanges and forming within the upper end of the tip-body a dischargechamber which is in communication with the hollow 2 of the tip-body 1.

10 l0 represent spaced lips or projecting flanges, which are extended around the adj acent edges of the curved or rounded sides 9 9 of the gas discharge chamber, being integrally produced upon the adjacent edges of said rounded sides 9 9 and being spaced apart to produce between them a slitted opening at which gas is adapted to be discharged from said chamber for producing an illuminatingfiame at the upper end of the improved burner-tip.

The lips or flanges l() 10 are extended slightly at angles to each other, as clearly `shown in Figs. 2 and 3, their relating inclinations being such that the slitted opening between them is made narrowest at the lower part of the gas-discharge chamber, as shown at 1l and widest at the apex of said chamber, as seen at 12 in Figs. 2 and 3. The said slitted o ening is thus given a tapered or wedgelike c aracter, so that the gas from the gasdischarge chamber will be emitted in much less volume at the lateral lower portions of the slitted opening and in gradually-increasing volume as the apex of said slitted opening is approached.

By means of the improved burner-tip constructed according to my invention it is possible to conveniently regulate the flow of gas from the pillar through the tip, so that the regulators commonly employed in the pillars may be readily dispensed with, a great convenience being thereby afforded in adjusting the regulating devices, since it is much less troublesome to remove the tip and adjust the contained regulating means than to remove the pillar for adjustment of regulating means therein. A

The construction of the gas-discharge chamber at the upper part of the tip is also of a very sim le character and increases the efficiency of t e burner in illumination by lessening resistance to the outflow of gas at the points where such outflow is most desirable, and the formation of the wedge-like or tapered gas-discharge slit serves to insure the greatest volume of discharged @as at the upper portions of the slit, so that tie discharged as is prevented from spreading laterally om the tip.

From the above descri tion of my improvements it will be evi ent that the improved burner-tip constructed according to my invention is of an extremely sim le and inexpensive nature and ,is especial y well l adapted for use, and it will `also `be vevident from the above description that the improved burner-tip is capable of considerable change without material departure from the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise form land arrangement of the several parts of the. device herein set forth in carrying out my invention in practice. ,tg-L,-

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A gas-burner tip comprising a tubular metallic body portion having a gas-passage produced in it, the u per end of said body -portion having inward y-directed parts at its p opposite sides and extended toward each other and forming flanges extended diametrically across the upper endof the body portion, said flanges being spaced apart to produce between them a slitted opening communicating with the gas-passage within the body portion for discharge of gas t`o be burned, said flanges being also extended vertically above the top of the body with plane inner faces of greater widt than the thickness of the metal from which the body portion .is formed to produce flattened side walls for said slitted opening.

2. A gas-burner tip comprising a tubular metallic body portion having a gas-passage produced in it, the upper end of said body portion having inwardly-directed parts at its opposite sides and extended toward each other and forming flanges extended diametrically across the up er end and downward along the sides of t e body portion, said flanges being spaced apart to produce between them a slitted opening and said opening being extended through the top and sides of the upper end of the body portion for communication with the gas-passage within the same for discharge of gas therefrom and said flanges being also extended at angles from the top and sides of the upper end of the body portion with plane inner surfaces wider than the thickness of the metal from which the body portion is produced and forming flattened side walls for said slitted opening.

3. A gas-burner tip comprising a tubular ortion metallic body portion having a gas-passage produced in it, the upper end of said body portion having inwardly-directed parts at opposite sides and extended toward each other and forming flanges extended diametrically across the top and downward along the sides of the upper end of thebody portion, said flanges being extended vertically above the top and laterallybeyond opposite sides of the top of the body portion and being spaced apart. to produce between them a slitted opening and said slitted opening being extended through the top and sides ofsaid upper end of the body portion for communi- 5 sage toward its upper part adjacent to the l Witnesses:
